BOTTLE-FINISHING MACHINE.

SPECIFICATION forming" part of Letters Patent No. 423,482, dated March 18, 1890.

Application filed June 11, 1888. Serial No. 276,769. (No model.)

To all whom it may concern:

Be it known that we, CHRISTIAN F. LENG and CHARLES LENG, citizens of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Finishing Machines; and we do hereby declare the following to be a'full,

such as Will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to an improvement in bottleneck-finishing machines; and it consists in a set of revolving dies for finishing the outer portion of theneck and a tapering opposite direction to that of the dies for finishing the inner portion of the bottle-neck,

together with certain details of construction and combination of parts, as will be fully set forth hereinafter.

In the accompanying drawings, Figure l is a plan view of our improved bottle-finishin g machine, partly shown in section, the better to show its working parts. Fig.2 is a side elevation of the same. Fig. 3 is an enlarged sectional elevation through a portion of the face-plate, showing the manner of securing and adjusting the dies. Fig. 4 is an enlarged detail sectional elevation showing the manner of attaching the guide-bar and face plate in position. I

To put our invention into practice we provide a frame A of suitable size and form of construction, and firmly attach thesame to a bench b. Mounted on this frame A and'secured in proper bearingst' are two shafts 0d, the one o centrally located within the other At the rear extremity of each of these shafts c d are secured bevel-pinions e, each of which meshes with a pinion f, properly mounted in a suitable bearing g on a short shaft 71. This arrangement of gearing serves to revolve the two shafts 0 din opposite directions. Secured to the forward end of the outside shaft (Z is a disk or face plate It, in which two finishing-dies Z are secured bypassing the same through openings m in the disk is conical-shaped clutch n, which, when moved forward on the outside shaft 61 by means of a neck of a bottle t placed between the same.

side shaft (1 between the bearings t' of the same, affords a means for operating the machine. These dies Z, guide-bar r, and the rectangular plate s may bedetached from the machine and others of different shape substituted, or the same dies 1 may be adjusted toward or away from each other by the setbottles. By this construction and operation the bottlet is preventedfrom turning in the dies Z when finishing the-same. The guidebar 1, revolving in one direction and the dies Z in an opposite way, equalize and counteract the friction of each other, thereby preventing a round bottle from turning and obviating the necessity of a device for clamping the same.

we claim, and desire to Patent, is-

1. In a machine for the purpose set forth, the combination of the-two shafts c d, the one centrally located within the other, and a means for revolving the same in opposite directions, the dies Z, adj ustably attached to the facesecure by Letters outside shaft (1, and adevice for opening and closing the same, the guide-bar r,jand rectangular washer s, secured to the inner shaft a, substantially as and for the purpose described.

2. In a machine for finishing the necks of bottles, the combination of the oppositely-rotating concentric shafts and the dies carried screws 0, to finish the necks of large or small Having thus described our invention, what plate is, secured to the forward end of the.

the rear of the face-plate k is a loosely-fitting A rod w, presses the dies l-together over the A tight and loose pulley y, secured to the out- A IOO by one of said shafts for finishing the exterior surface of the neck of the bottle, substantially as and for the purpose described.

3. In a machine for finishing the necks of bottles, the combination'of the oppositelyrotating concentric shafts, the finishing-dies carried by one of said shafts, and a guide carried by the other shaft to center theneck of the bottle between said dies, substantially as and for the purpose described.

4. In a machine for finishing the necks of bottles, the combination of the concentric oppositely-rot'ating shafts, a face-plate carried by one of the shafts, the finishing-dies movably mounted in said face-plate, and a sliding device for simultaneously adjusting said dies, substantially as and for the purpose described. I

5. In a machine forfinishing the necks of bottles, the combination of the concentric oppositely-rotating shafts, a face-plate fixed to one of saidshafts, the finishing-dies loosely mounted in the face-plate, a conical sliding sleeve adapted to impinge against all of said I dies to simultaneously adjust the same, anda stop for limiting the inward movement of the dies upon the neck of the bottle, substantially as described.

6. Ina machine for finishing the necks of bottles, the combination of thecon'centric rotary shafts, a forwardly-projecting guide carried by one of the shafts, a face-plate fixed to the other shaft, the finishing-dies loosely fitted in apertures in said face-plate, and adjusting-screws for moving the dies laterally of one another, substantially as described.

7. In a machine for finishing the necks of bottles, the combination of the concentric rotary shafts each having a pinion secured thereto which mesh with another pinion, a faceplate fixed to the hollow shaft and carrying the movable finishing-dies, a sliding conical sleeve for simultaneously adjusting
